3 Claims.

This invention relates to jacks, and more particularly has reference toa jack especially designed for jacking up an automobile spring tofacilitate repairing and/ or removing the spring.

An object of the present invention is to provide a jack of thischaracter that is characterized by simplicity of construction, minimumof parts, and which at the same time will prove well adapted for thepurpose intended.

The invention together with its objects and advantages will be bestunderstood from a study of the following description taken in connectionwith the accompanying drawings wherein:

Figure 1 is a side elevational view illustrating the application of thejack.

Figure 2 is a fragmentary detail sectional View taken substantially onthe line 2-2 of Figure 3.

Figure 3 is a top plan view of the jack with certain parts removed andother parts shown in section.

Figure 4 is a fragmentary enlarged detail view partly in section andpartly in elevation and illustrating certain details of constructionhereinafter more fully referred to.

Figure 5 is a plan view of a threaded shank forming part of theinvention, and

Figure 6 is a detail sectional View taken substantially on the line 6-6of Figure 2.

Referring more in detail to the drawings it will be seen that in thepreferred embodiment thereof the jack comprises a base 5 that in thepresent instance is in the form of a rectangular frame made of wood orany other suitable material.

A pair of spaced parallel pivot bolts Ii6 extend transversely of theframe 5 intermediate the ends of the frame, the sides of said framebeing suitably apertured to accommodate the bolts.

Pivotally connected to the frame 5 through the medium of the bolts 6 arejack rods 'I-I.

Each jack rod 1 is of tubular construction and is provided at one endwith an integral laterally extending hub 8 which accommodates a pivotbolt 6 as shown.

Each jack rod I telescopically accommodates a threaded shank 9 that isrestrained against rotative movement relative to its associated rod 1,and constrained to shift longitudinally of the associated rod I throughthe medium of a lateral pin I0 extending from the inner end of the shank9 and working in a longitudinal slot II provided therefor in the red I,as clearly shown in Figure 4.

For adjusting the shank 9 relative to its associated rod 1 there isprovided an operating nut I2 equipped with handles I3 to facilitateturning of the nut. Obviously, as the nut I2 is turned in a properdirection the shank I will be caused to thread therethrough inwardly oroutwardly, as desired, with respect to the associated jack rod I.

For engagement with the vehicle spring I4 adjacent the eyes I5 0f thespring the shanks 9 at their outer free ends are smooth and flattened asat I6.

The manner of using the jack may be briefly described as follows:

When it is desired to perform some work on the vehicle spring I4, or toremove the spring, necessitating the removal of the shackles, the base 5is positioned on the ground as shown in Figure 1, and the jack rods Iextended in opposite directions to substantially align with theeyeequipped ends of the spring I4. The nuts I2 are then rotated in theproper direction for feeding of the shanks 9 to engage the ends I6thereof with the underside of the spring I4 immediately adjacent to theeyes I5 of the spring. Obviously the shanks 9 may be adjusted outwardlywith respect to the jack rods I to the extent desired for maintainingthe spring I4 in a position or condition facilitating the removal of thespring shackles and the performance of the work desired.

Obviously when no further use of the jack is required, the nuts I2 arerotated in a reverse direction for causing the shanks 9 to retractinwardly with respect to the rods I so that the ends I6 of the shankswill clear the eyes I5 permitting bodily removal of the jack to anout-of-the-way place.

It is thought that a clear understanding of the construction, manner ofuse, utility and advantages of an automobile spring jack embodying thefeatures of the present invention will be had without a more detaileddescription.

Having thus described the invention what is claimed as new is:

1. A vehicle leaf spring supporting and repairing jack comprising asupporting base of skeleton frame structure, tubular jack rods pivotedat one end thereof to the base inwardly from opposite ends thereof so asto be angularly swingable to and from said base, shank memberstelescopically fitting in said jack rods, interengaging means on saidjack rods and said shanks for extending and retracting said shanksrelative to said jack rods and for securing said shanks at the desiredposition of adjustment, and each of 66 said shanks having a flatttenedfree end for engagement with an automobile spring adjacent to a terminaleye of said spring.

2. A jack particularly designed for jacking up automobile springs, saidjack comprising a base frame, a pair of tubular jack rods pivoted at oneend thereof to said base so as to be bodily and angularly swingablerelative to said base, a threaded shank slidably fitting each jack rod,interengaging means on said shank and associated jack rod restrainingsaid shank against rotative movement relative to the jack rod, and ahandle equipped nut threadedly engaged above the shank and bearingagainst an end of the jack rod for projecting and retracting said shankwith respect to its associated jack rod.

3 An automobile spring jack comprising a substantially rectangular baseframe, a pair of spaced parallel pivot bolts mounted in the frametransversely thereof inwardly from the ends of the frame, tubular jackrods respectively provided at one end with an integral laterallyextending hub embracing one of said pivot bolts, threaded jack rodshaving telescopic engagement with said tubular jack rods, said tubularjack rods having longitudinal slots in the peripheries thereof, and saidthreaded jack rods having lateral pins extending therefrom and engagingin said slots whereby said threaded jack rods are constrained againstrotative movement relative to the tubular jack rods, and handle equippedoperating nuts threadedly engaged on the threaded jack rods and bearingagainst the free ends of the tubular jack rods for projecting andretracting said threaded jack rods with respect to said tubular jackrods.
